Specification of Letters Patent.

Patented Aug. 18, 190s.

Application filed September 30, 1907.` Serial No. 395,196.

To all whom it may concern:

Be it known that I, MILES E. FREEMAN, a citizen of the United States,residing at Bradford, in the county of McKean and State of Pennsylvania,have invented certainl new and useful Improvements in PneumaticDust-Removers and I do declare the following .to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same. L ,j

My invention relates to pneuniatic carpet cleaning apparatus, and moreparticularly to dust collecting nozzles adapted to be brought intocontact with the object to be cleaned, and its novelty consists in theconstruction and adaptation of the parts, as will be more fullyhereinafter pointed out.

In the accompanying drawings,-Figure 1 is a top plan view of a nozzleembodying this invention; Fig. 2 is a longitudinal section taken on line2-2 of Fig. 1; Fig. 3 is a cross sectional view taken on line 3 3 ofFig. 2; Fig. 4 is a horizontal section taken on line 4-4 of Fig. 3.

Referring to the drawings, a pipe 10 is adapted to be connected with thenozzle 20 in any suitable manner, and is connected at 4its other end toa suitable hose, (not shown),

which, in turn, leads to a vacuum-producing means, such as a fan orpump, (not shown).

The nozzle 20 comprises a throat 21, constructed of the side walls 22,22 and the end walls 23, 23,'and restricted laterally to form a neck 24,which is threaded at 25to engage with the threaded end of the suctionpipe 10. l

The neck 24 is bent at 26 to render the device more convenient for theoperator to handle and to move over the carpet or other surface to beltreated.

Transversely arranged between the walls 22, 22 and 23, 23`is'a diaphragm30, perforated at 31, 31 to permit of the passage of the air and dustthrough the same to the throat 21. Beyond this diaphragm is a mouth 40,formed ofthe jaws 41, 41, and within said mouth is arranged anintermediate tongue 42, which extends from the 'diaphragm 30,

which forms the rear wall of said mouth.

' In the construction shown, the jaws 41, 41 are made integral with theside walls 22, 22 and form a portion thereof, and the tongue 42 is madeintegral with the diaphragm 30,

and is placed substantially at right angles thereto. r

The mouth 40 is divided into two compartments 43 and 44 by theintermediate tongue 42, and this tongue 42 serves the function of ascraper against the surface of the carpet or other object to becleaned'.

In the use of this device, the vacuum producing means being inoperation, the workman' places the nozzle against the carpet insubstantially the manner shown in Figs. 2 and 3, with the tongue 42 andthe jaws 41, 41 resting thereon. The nozzle being then drawn over thecarpet 50, the nap is raised and the dust agitated thereby enabling thedust to be rapidly drawn first into the compartments 43 and 44, andthence through the apertures 31, 31 into the throat 21,. whence it isdrawn into the pipe 10 and from there is conveyed to the lfinal place ofdeposit.

I claim as my invention A nozzle for a pneumatic carpet cleaner, havingparallel walls and an apertured diaphragm within its interior, andprovided with a tongue extending parallel with the UESSES.
